Apparatus for cooling an exerciser for use with an exercise machine

ABSTRACT

An apparatus is disclosed that cools an exerciser using an exercise machine by blowing chilled air directly onto the exerciser from an airflow director that is independent of the exercise machine. The airflow director is either located within the living space of the exercise room, or able to project a directed stream of chilled air into the living space of the exercise room. The airflow director can include adjustments for chilled air direction, flow rate, and other qualities. The chilled air source can include adjustments for temperature, humidity, and other qualities. A plurality of airflow directors can be included, so as to provide uniform cooing and/or to deliver chilled air to a plurality of exercise machines. A barrier and/or chilled air return vent can be included, so as to save energy and enhance the localization of the chilled air. Some embodiments can also warm the exerciser using warmed air.

FIELD OF THE INVENTION

The invention generally relates to exercise machines, and more specifically to devices for cooling an individual while using an exercise machine.

BACKGROUND OF THE INVENTION

Exercise is generally known to have many benefits for individuals of all ages. These benefits include improved cardiovascular health, reduced blood pressure, prevention of bone and muscle loss, maintenance of a healthy weight, improved psychological heath, and many others. However, exercise is generally accompanied by a certain degree of discomfort, including overheating, sweating, fatigue, etc, and this leads to a significant reduction in the amount of exercise undertaken by many individuals, thereby reducing the health benefits derived from exercise.

Because of weather variability, convenience, and time constraints, exercise often takes place indoors using an exercise machine such as a stepper, stationary bicycle, elliptical, treadmill, etc. Attempts are sometimes made to increase the comfort of exercising individuals in these environments by optimizing the surrounding temperature, but this can be largely unsatisfactory because exercisers generally require different degrees of cooling depending on individual physiology and on how long and how vigorously they have been exercising. If the surrounding air is warm enough to be comfortable for individuals just beginning an exercise session, it will be too warm for individuals well into a vigorous session. And if the surrounding air is cool enough to be comfortable for an individual who has been exercising vigorously for a significant amount of time, it will be too cold for individuals just beginning to exercise.

Some exercise machines include a fan that can direct a flow of air onto some portion of an exerciser's body during exercise, thereby providing a certain degree of cooling that can be initiated and controlled by the exerciser. However, such fans can provide only a small amount of cooling, and they are typically limited to cooling only the face of the exerciser, and/or some other fixed, limited region of the exerciser's body. Also, many exercise machines do not include any facilities for cooling an exerciser, and it can be prohibitively expensive to replace an exercise machine merely for the purpose of obtaining a similar exercise machine that includes a cooling fan.

Another approach is to place an exercise machine near a fixed vent of a built-in air conditioning system. However, this requires that such a vent be available in a convenient location. If a plurality of exercise machines are to be placed within the same room, it is highly unlikely that each of them can be placed near a conveniently located air conditioning vent. Fixed air conditioning vents and ducts are typically either built into a wall, floor, or ceiling, or they are mounted directly onto a wall, floor, or ceiling. In all such cases, vents and ducts for built-in air conditioning systems are located within a space that can be considered not to be part of the “living space” of a room, even though the vent, and even the duct, may be visible from within the room. This places significant limits on how closely an exercise machine can be placed to an outlet vent of a built-in air conditioning system. And even when an exercise machine can be placed near a conveniently located air conditioning vent, the vent is typically not configured so as to direct a localized flow of cooling air that can be directed specifically onto an exerciser using the exercise machine.

Yet another approach is to position a fan or portable air conditioner on the floor, on a table, or on some other support near an exercise machine, and to direct therefrom a flow of cooling air toward the exercise machine. However, a fan can provide only limited cooling, and a portable air conditioner provides only a very limited ability to target the local environment of an exerciser.

If a plurality of exercise machines are arranged in close proximity to one another, a portable air conditioner directed toward one of the exercise machines will necessarily tend to affect the environment of nearby exercise machines, thereby reducing the ability of each exerciser to control his or her individual exercise environment. Even if only a single exercise machine is present, it is difficult or impossible using a portable air conditioner to cool only the region immediately surrounding an exerciser. As a result, energy will be wasted and cost will be increased in cooling the entire room in which the exercise machine is located.

SUMMARY OF THE INVENTION

An apparatus is disclosed for cooling an exerciser while using an exercise machine in an exercise room. The apparatus includes an airflow director that is either located within the living area of the exercise room and able to direct chilled air onto an exerciser while using the exercise machine, or supported by a wall, the floor, or the ceiling of the exercise room, and able to project a directed stream of chilled air directly upon the exerciser. The airflow director is connectable to a chilled air source by an air duct. In preferred embodiments, the airflow director can be free standing and movable, or fixed to an adjoining structure such as a wall or ceiling.

Various embodiments include a plurality of independent airflow directors that enable chilled air to be directed onto the exerciser from multiple directions, thereby improving the efficiency and uniformity of cooling of the exerciser while improving the localization of the cooling to the immediate region of the exercise machine. In some embodiments, a partial wall or other structure is included that tends to confine the chilled air to a region immediately surrounding the exerciser. Other embodiments include an air return vent that removes and recirculates chilled air from the region surrounding the exerciser, thereby limiting the impact of the chilled air on other, nearby exercisers and on the surrounding environment.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

With reference to FIG. 1, approaches known in the prior art for cooing an exerciser using an exercise machine 100 include cooling fans 102 that are built into a portion 104 of the exercise machine, as well as stand-alone cooling fans 106, mounted for example on floor stands 108, and able to direct a flow of air 110 onto the exerciser. However, a flow of ambient air propelled by a fan provides only limited cooling of an exerciser.

With reference to FIG. 2A, the present invention 200 includes an airflow director 202 located within a living region of an exercise room that is able to blow chilled air directly onto an exerciser while the exerciser is using an exercise machine 100. In the preferred embodiment of FIG. 2A, the airflow director 202 is supported by a moveable floor stand 204. An air duct 206 is connectable to a source of chilled air 208, which in the embodiment of FIG. 2A is a portable air conditioner. The air duct 206 delivers the chilled air to the airflow director 202. Warm air generated by the portable air conditioner 208 is exhausted through an exhaust duct 210 to a location outside of the room.

A close-up view of the airflow director 202 of FIG. 2A is shown in FIG. 2B. In this embodiment, a pair of manually controlled knobs 212, 214, control the pitch of a set of horizontal and vertical louvers 216, thereby controlling the direction and the flow rate of chilled air directed by the airflow director 202 onto an exerciser.

FIG. 3 illustrates an embodiment similar to the embodiment of FIG. 2A, but including a chilled air return vent 300 positioned opposite to the airflow director 202 so as to withdraw and recirculate the chilled air 302 after it has cooled the exerciser, thereby increasing the localization of the cooling and conserving energy. For simplicity of illustration, the exercise machine has been omitted from the figure.

FIG. 4 illustrates an embodiment similar to FIG. 2A, but including a pair of airflow directors 202, one supported by a movable stand located behind the exerciser 400, and the other attached to an entertainment stand 404 that is also supporting a television screen 406 that can be viewed by the exerciser 400 during exercise. The pair of airflow directors 202 in this embodiment provide a more uniform cooing of the exerciser, as compared to the single airflow director 202 of FIG. 2A.

FIG. 5A is a top view of a prior art approach in which an exercise machine is simply placed near a cooling vent 500 of a built-in air conditioning system. In FIG. 5A, the cooling vent 500 and a corresponding cooling air duct 502 are built into a wall 504 of the exercise room. The vent is therefore well outside of the living area of the room, which is separated from the walls by the imaginary boundary 506 shown in the figure. FIG. 5B is a top view of a similar prior art approach, in which the cooling vent 500 and duct 502 are attached to the wall. While the vent 500 and duct 502 extend into the room and are visible from the room, they are closely attached to the wall 504 and do not extend beyond the boundary 506 and into the living area of the room.

In the prior art approaches illustrated by FIG. 5A and FIG. 5B, the cooling vents 500 cannot be placed close enough to the exercise machine 100 to provide localized cooling of the exerciser. In addition, cooling vents 500 included with built-in air conditioning system are typically designed to disburse cooling air so as to uniformly cool the interior of an entire room, rather than locally cooling only one area of a room.

FIG. 5C is a top view of a preferred embodiment of the present invention in which the airflow director 202 is suspended from a wall 504 by a duct 206 that extends from the wall through the boundary 506 and into the living area of the exercise room. The airflow director 202 is thereby placed close to an exerciser using the exercise machine 100, and can be specially designed to direct chilled air onto the exerciser.

FIG. 5D and FIG. 5E are side views of prior art approaches that are similar to FIG. 5A and FIG. 5B, respectively, except that the cooling air vent 500 and duct 502 are located either within the ceiling 508 of the exercise room (FIG. 5D) or are attached to the ceiling 508 of the exercise room (FIG. 5E). As in FIG. 5A and FIG. 5B, the cooling vents 500 cannot be placed close enough to the exercise machine 100 to provide localized cooling of the exerciser, and the cooling vents 500 are typically designed to disburse cooling air so as to uniformly cool the interior of an entire room, rather than locally cooling only one area of a room.

FIG. 5F is a side view of a preferred embodiment of the present invention that is similar to FIG. 5C, except that the airflow director 202 is suspended from the ceiling of the exercise room 508 by a duct 206 that extends from the ceiling through the boundary 506 and into the living area of the exercise room. As in FIG. 5 c, the airflow director 202 is thereby placed close to an exerciser using the exercise machine 100, and can be specially designed to direct chilled air onto the exerciser.

FIG. 5G is a side view of a preferred embodiment similar to FIG. 5C, except that the airflow director 510 is built into the wall 504 of the exercise room. However, unlike the prior art approach of FIG. 5A, the airflow director of FIG. 5G is designed to project a directed stream 512 of chilled air directly upon an exerciser using the exercise machine 100, while the vent 500 of a typical air conditioning system, as shown in FIG. 5A, is typically designed to disburse chilled air so as to cool a room as uniformly as possible.

FIG. 5H is a side view of a preferred embodiment similar to FIG. 5C, except that the airflow director 510 is attached to a duct 502 that is fixed to the wall 504 of the exercise room. Unlike the prior art approach of FIG. 5B, the airflow director of FIG. 5H is designed to project a directed stream 512 of chilled air directly upon an exerciser using the exercise machine 100, while the vent 500 of a typical air conditioning system, as shown in FIG. 5B, is typically designed to disburse chilled air so as to cool a room as uniformly as possible. In the specific embodiment of FIG. 5H, the airflow director 510 is configured at an angle so as to direct the flow of chilled air 512 partly from behind the exerciser.

FIG. 5I is a side view of a preferred embodiment similar to FIG. 5F, except that the airflow director 510 is built into the ceiling 508 of the exercise room. However, unlike the prior art approach of FIG. 5D, the airflow director of FIG. 5I is designed to project a directed stream 512 of chilled air directly upon an exerciser using the exercise machine 100, while the vent 500 of a typical air conditioning system, as shown in FIG. 5D, is typically designed to disburse chilled air so as to cool a room as uniformly as possible. In the specific embodiment of FIG. 5I, the airflow director 510 is configured at an angle so as to direct the flow of chilled air 512 from above and partly from behind the exerciser.

FIG. 5J is a side view of a preferred embodiment similar to FIG. 5F, except that the airflow director 510 is attached to a duct 502 that is fixed to the ceiling 508 of the exercise room. Unlike the prior art approach of FIG. 5E, the airflow director of FIG. 5J is designed to project a directed stream 512 of chilled air directly upon an exerciser using the exercise machine 100, while the vent 500 of a typical air conditioning system, as shown in FIG. 5E, is typically designed to disburse chilled air so as to cool a room as uniformly as possible.

FIG. 6A is a top view of a preferred embodiment that includes a physical barrier 600 that partly surrounds the exercise machine 100 so as to enhance the localization of the chilled air 302 to the region immediately surrounding the exercise machine 100. In the embodiment of FIG. 6A, the airflow director 202 is contained within one side of the barrier 600, and a chilled air return vent 300 is located opposite to the airflow director 202 on the other side of the barrier 600. This arrangement causes chilled air to flow directly across an exerciser using the exercise machine 100 and then to be recirculated, saving energy and enhancing the localization of the chilled air to the area immediately surrounding the exerciser.

FIG. 6B is a top view of an embodiment similar to FIG. 6A, except that a chilled air return vent is not included, and a second airflow director 202 is included so as to provide more uniform cooling of the exerciser by providing flows of chilled air from both sides of the exerciser. FIG. 6C and FIG. 6D are top views of embodiments similar to FIG. 6A and FIG. 6B, except that an airflow director 202 and a chilled air return vent 300 is provided in each half of the barrier 600, thereby providing uniform cooling and enhanced localization of the chilled air and enhanced energy efficiency.

FIG. 6E is a perspective view of one-half of an embodiment similar to the embodiment of FIG. 6A, except that a plurality of airflow directors 202 is provided in the wall of the barrier 600. In this embodiment the airflow directors 202 are independently adjustable, and include independently adjustable fans, so as to provide enhanced flexibility for an exerciser to configure the cooling provided by the invention according to the physiological needs and preferences of the exerciser. For example, one exerciser may wish to direct relatively more chilled air onto his or her legs, while another exerciser may wish to direct more chilled air onto his or her face. The opposite half of the barrier 600 has been omitted from the drawing for clarity of illustration.

FIG. 7 illustrates an embodiment in which a plurality of airflow directors 202 and chilled air ducts 204 draw chilled air from a common source and direct the chilled air onto a plurality of exercise machines 100. In the embodiment of FIG. 7, the airflow directors 202 are vertically elongated as compared to the airflow directors of FIG. 2A, so as to provide localized cooling of the length of an exerciser's body. Barriers 600 are attached to the airflow directors 202, so as to enhance the localization of the chilled air to each exercise machine. This allows each exerciser to control the cooling of his or her local exercise environment according to individual physiologies and preferences.

FIG. 8 illustrates a preferred embodiment that includes a plurality of airflow directors 202 supported by air ducts 204 that are attached to the ceiling 508 of the exercise room and extend past the imaginary barrier 506 and into the living area of the exercise room in a manner similar to FIG. 5F. The plurality of airflow directors 202 are positioned above a plurality of exercise machines 402, with one airflow director 202 dedicated to each exercise machine 402. A chilled air return vent 300 is provided in the floor 800 beneath each exercise machine 400 so as to save energy and enhance the localization of the chilled air to each of the exercise machines 402. A remote control 802 is attached to each exercise machine 402, and is in wireless communication with a corresponding chilled air controller 804 located in the ceiling 508 above each air duct 204. This allows each exerciser 400 to control the amount of chilled air 302 that is blown directly upon the exerciser 400.
